WINDING ATTACI-DWENT FOR COPYING-MACHINES.

Specification o1? Letters Patent.

Patented May 1 1, 190e.

T 0 all whom it' may concern:

Be it known that we, FRIEDRICH SORN- NECKEN, a subject of the King of Prussia, German Emperor, and resident of 1 Kirschallee, Bonn-on-the-Rhine, Germany, and ED WARD CHARLES MAGNUs, a citizen of the United States of America, and resident of 5 Jagdweg, Bonn-on-the-Rhine, Germany, have invented certain new and useful 1mrovements in Winding Attachments for opying-Machines, of which the following is a specification.

This invention relates to copying machines and is directed toward improvements in the means used for collecting the single moist sheets of copying paper. 1t has already been proposed to pass such sheets at short intervals apart to a roller where the sheets are wound together with any suitable form of web. In this way the sheets are etticiently dried.

The object of the present invention is to provide an improved arrangement of winding-on device for the copying machine.

The invention is also directed toward iinproved details in connection with the winding-on device.

According to the present invention the copying paper is as regards operation retained in web form until the copying paper enters the winding roll. This result is effected by arranging the winding-on roller below the exit point from the copying machine and at a distance less than the smallest length of copying sheet. The winding-on web which is passed to the winding-on roller is guided over a cylinder arranged above the winding-on roller so as to form a pocket into which the moist copying sheets pass. The winding-on web is passed from a supply roller over the guiding cylinder referred to above and for the purpose of returning the web from the winding-on cylinder to the sup ly cylinder a ratchet and pawl driving mec anism is employed for the winding-on roller as hereinafter more particularly dee scribed.

Referring now to the accompanying drawings Figure 1 is a diagrammatic side elevation of the copying machine provided with winding-on apparatus according to the present invention, Fi 2 is a plan of the windingon apparatus inc uding one of the rollers of the copying machine, Fig. 3 is a detail view showing the ratchet and pawl driving mech:

anism for the winding-on roller, Fig. 4 is a sectional elevation of the ratchet and pawl driving mechanism shown in Fig. 3.

1n carrying the invention into eifect according tc the form shown a roll of copying paper 5 is journal/ed between side frames 6 of the copying machine. From the roll 5 the thin copying paper passes over a guide roller 7, is suitably moistened and then passes between the pressing rollers 8 and 9, the lower roller 8 of which is driven by a handle 10. Over the roller S there passes a tape or the like which also passes between the rollers 11 and 12. The roller 11 is driven from the roller 8 through a band 19, and as can be seen from the drawings the driving pulley of the roller 11 is slightly smaller than the driving pulley on the roller 8 so that the roller 11 moves with a slightly greater circumferential velocity than the roller 8. The paper web passing from the roller 5 is perforated or otherwise weakened at suitable places so that when the paper is gripped by the rollers 11 and 12 which act as dividing rollers the sheets 13 are separated from the paper web. rEhe sheets 13 which are moist and heavy after passing over the roller 11 naturally hang easily downward without any tendency of turning up or crumpling. As short a distance as possible below the exit point from the rollers 11 and 12, which also forms the exit point for the sheets from the copying machine, there is arranged the winding-on roller The winding-on roller is supplied with a winding-on web from a roller 15 and this web passes over guide cylinders 15 and 17 to the winding-on roller 14. The guide cylinder 17, which may be in the form of a cylindrical bar or a rotatable roller as shown', is arranged above the axis of the roller 141 and guides the winding-on web 18 to the windingpn roller 14 in such a manner that a pocket is formed vertically below the exit point from the copying machine. Into this pocket the moist single sheets of copying paper pass. The winding-on web 1S may be made of any absorbent material or may be composed of wires so as to facilitate the drying of the sheets on the roller 141. Owing to the fact that the rollers 11 and 12 move more quickly than the rollers S and 9 the sheets 13 are spaced ashort distance apart as can be seen from Fig. 1. rEhe arrangement of the parts described is such that the supply roller 15 lies beneath the copying machine as also does the Winding-on roller 14. 1n this way the machine is extremely compact and the sheets are efficiently guided into the winding-on roller 14 without danger of the same being bent or crumpled.

For the purpose of driving the winding-on roller 14 a cross band 20 is passed from the driving roller 8 of the copying machine. The cross band 20 passes over a pulley 21 which is i'ixed on the shaft 22 on which the winding-on roller 14 is loosely liournaled. r1`he winding-on roller 14 is driven from the shaft 22 through the ratchet and pawl mechanism illustrated in detail in Figs. 3 and 4. On the shaft 22 there is fixed a ratchet Wheel 24 with which ratchet pawls 25 engage. The ratchet pawls 25 are carried by the arms 26 of the winding-on drum or roller 14. Three ratchet pawls 25 are shown and these pawls are provided with pins 27 to which springs 28 are fixed. The s rings 28 form connections between the paw s to press the same to the ratchet wheel. Passing loosely over the end of the shaft 22 there is a sleeve 29 to which a disk 30 is attached. The disk 30 is provided with pins 31 which extend laterally so as to come into the plane in which the pawls 25 are arranged. The pins 31 project behind the pawls 25 and when the disk 30 is moved in a counter clockwise direction in Fig. 3 the pins 31 engage against nose pieces 32 formed on the pawls. ln this way the pawls are raised from engagement with the ratchet Wheel 24. The counter clockwise motion of the disk 30 may be effected by removing the handle 10 from the roller 8 and passing it over the hub 29. A feather 33 on the hub 29 serves the purpose of keying the handle 1() to the hub 29. lt will be seen with this arrangementthat normally when the machine is in use the winding-on roller 14 is driven through the cross band 20 and for the purpose of unwinding the winding-on web 18 from the roller 14 the handle crank 10 is inserted on the hub 29. The disk 30 is rotated in a counter clockwise direction so that the iirst part of the motion removes the pawls 25 from engagement with the ratchet wheel 24 and then the pawls 25 act as coupling pieces between the pins 31 and the drum 14 so that the drum is also rotated in a counter clockwise direction. This counterl clockwise rotation is communicated to the supply roller 15 by means of a driving cord or the like 34. The driving member 34 passes over a pulley 35 which carries a pawl 36. The pawl 36 is adapted to engage the teeth of a ratchet wheel 37 'fixed to the roller 15. The roller 15 is as can be well understood loosely mounted on its axle or shaft 38. N ith this arrangement the roller 15 is free to rotate in the direction of unwinding of the winding-on web i. e. during normal use of the machine. When, however7 the winding-on web is to be unwound from the roller 14 and returned to the supply roller 15 by the means described above the supply roller 15 is positively driven through the ratchet and pawl 36, 37.
